I'm finally releasing some new PPU VBL/NMI timing information and test ROMs. These tests brutally test to single PPU clock accuracy, unlike previous PPU timing tests, so there's no room for error here. Please note that these test only one of the random timing arrangements at power-up (there are others with more special cases, but I haven't spent time determining them).

As usual, post questions about the test ROMs themselves here, and questions about proper PPU operation in a separate thread.
